JanusGraph is a fork of the popular open source project Titan, originally released in 2012 by Aurelius, and subsequently acquired by DataStax. Titan has been widely adopted for large-scale distributed graph computation and many users have contributed to its ongoing development, which has slowed down as of late: there have been no Titan releases since the 1.0 release in September 2015, and the repository has seen no updates since June 2016.

This new project will reinvigorate development of the distributed graph system to add new functionality, improve performance and scalability, and maintain a variety of storage backends.

The name "Janus" comes from the name of a Roman god who looks simultaneously into the past to the Titans (divine beings from Greek mythology) as well as into the future.

All are welcome to participate in the JanusGraph project, whether by contributing features or bug fixes, filing feature requests and bugs, improving the documentation or helping shape the product roadmap through feature requests and use cases.
